To account for power losses assume an 80 percent efficiency. Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array.
Inverters play a vital role in converting the direct current (DC) generated by your solar panels into usable alternating current (AC) for your home. Selecting the proper inverter size ensures that your solar system operates at its full potential, ultimately impacting energy savings and system longevity.
Knowing your array size allows you to choose an inverter that can handle that production efficiently—without over- or under-investing in capacity. The second step is understanding your system’s DC-to-AC ratio, one of the most important metrics when sizing a solar inverter.
A good rule of thumb is to multiply the total wattage of your solar panels by 1.25 to account for inefficiencies and potential load spikes. For example, if you have a 5 kW solar system, you would need an inverter rated for at least 6.25 kW. Q: What happens if my inverter is too small for my solar panel system?
